In this tutorial, we will discuss how to change users in a MySQL environment. Changing users is a common task when managing MySQL databases, as different users typically have different privileges, which depend on the requirements of a given situation.

The ability to switch users can prove highly beneficial when trying to troubleshoot issues, adjust settings, or manage data. Follow the steps below for a seamless user-switching experience in MySQL.

Step 1: Log in to MySQL

The first step is to log in to the MySQL command line client with the current user credentials. To do so, open a terminal or command prompt and enter the following command:

Replace current_user with your current MySQL username. After hitting enter, you will be prompted to enter your password. Type it in and you will be logged in to MySQL.

Step 2: Review current user privileges

Before switching users, it’s a good idea to check the current user’s privileges. Knowing your current privileges will help you determine if the new user offers the capabilities you need. To view your privileges, run the following command in the MySQL shell:

This will display the list of privileges assigned to the currently logged-in user.

Step 3: Log out of MySQL

Now that you know your current user privileges, log out of MySQL by entering the following command:

This will return you to the terminal or command prompt.

Step 4: Log in as a new user

With your current user logged out, it’s time to log in as a new user. Enter the following command, replacing new_user with the desired MySQL username:

Enter the password for the new user when prompted, and you will be logged in to MySQL as the new user.

Step 5: Verify the new user

Once logged in as the new user, verify your new username by running the following command in the MySQL shell:

This command will show the active MySQL user to confirm that you’ve successfully switched users.
